Definitions

• the invention relates to a security element for a security document, such as a bank note, ID card or the like, consisting of a translucent carrier material which has an opaque layer with recesses in the form of characters, patterns or the like which can be recognized in transmission, and a magnetic layer which is located under the opaque layer is arranged.
• EP 0 407550 AI describes a security document with an embedded security thread that is provided with a binary code made of magnetic material.
• certain bit lengths are defined which are constant over the entire length of the strip. The assignment of a bit length with magnetic material corresponds, for example, to 1, while a bit length not provided with magnetic material corresponds to 0.
• the binary code known from EP 0 407550 AI is now distinguished by the fact that it is composed of alternatingly arranged separating segments and word segments, the word section consisting of a certain number of bit lengths and the sequence of the binary values of the separating segments not being allowed to occur within this word length, to enable a clear recognition of the word segments.
• this security element has the disadvantage that it is not an option for provides a quick visual check as is necessary in many everyday situations.
• a security document with such a security element is already known from EP 0 516 790 AI.
• the security thread described here consists of a transparent plastic carrier layer with a metallic coating, in which recesses are provided in the form of characters or patterns, the so-called “negative writing”. These recesses and the metallic environment are provided the thread is present in the paper pulp When viewed in transmitted light, however, the translucent cutouts stand out in stark contrast to their opaque surroundings and are therefore clearly visible.
• the security element has a magnetic coating, for example underneath the metal layer in the edge areas of the thread and is provided symmetrically to the recesses along the running direction of the element in the document.
• the invention is based on the object of proposing a security element which offers increased protection against counterfeiting and at the same time is simple to produce.
• the invention is based on the idea of combining the advantages of the visually verifiable negative writing and the machine-readable magnetic coding and of the special mutual assignment on the security to guarantee increased counterfeit protection compared to the individual security features.
• the security element according to the invention therefore consists of an at least translucent plastic layer which has an opaque layer with cutouts and a magnetic coding, the cutouts being arranged in the areas of the element which are free of magnetic layers.
• the special geometrical arrangement of the cutouts and the magnetic areas can consist, for example, of the coding and cutouts being nested, i.e. the magnetic layer-free portions of the coding are used to arrange the visually verifiable negative characters in this area.
• the security element is in the form of a thread or strip that is at least partially encased in a document material, such as e.g. Banknote paper, is embedded, or can also be arranged on the surface.
• a document material such as e.g. Banknote paper
• the security element is arranged on the surface of the document material, it is not absolutely necessary to prepare all the layers necessary for the authenticity detection on a separate carrier. If the security element has an optically effective layer, such as a diffraction structure or interference layer elements, it is necessary to smooth the surface of the document material in the area of the security element, since surface roughnesses have the optical effect and the brilliance of the element. This is often done by applying an underlying layer, for example a layer of lacquer. The magnetic material can now also be introduced into this layer.
• an optically effective layer such as a diffraction structure or interference layer elements
• this background layer can be applied in two passes.
• a magnetic material is added to the first layer to be applied and this layer is then discontinuously, e.g. applied in the form of a barcode.
• the second layer is arranged over the entire surface of the first layer and is composed in such a way that optimal adhesion between document material and other marking layers to be applied, e.g. a hologram is generated.
• the security element is preferably designed in the form of a strip.
• FIG. 13 shows a section along A - A through the security document according to FIG. 12.
• a security document 1 such as a banknote, in which a security element 2 in the form of a so-called window security thread is embedded.
• the security thread 2 is virtually woven into the paper mass during paper manufacture, so that it comes directly to the document surface at regular intervals, which is indicated by the hatched boxes.
• Fig. 2 shows in principle the external appearance of the security element
• the magnetic coding 20 is covered by the opaque layer 3 and can therefore not be located without additional aids. However, it must be arranged in a region of the element 2 in which there is no negative writing 4 in order not to impair the optical effect of the negative writing 4.
• the elevation in area 6 shows that the magnetic coding 20 is arranged parallel to the recesses 4 in this case. Both the coding 20 and the cutouts take up about half the thread width.
• the coding 20 is composed of magnetic areas 5 and non-magnetic areas 15 and can be arranged several times on the security element 2.
• the coding 20 is preferably repeated continuously along the element 2.
• FIG. 3 A section along A - A through this thread is shown in Fig. 3.

• a thread that is embedded in the document material it is usually a plastic film that preferably has a thickness of approximately 10 to 20 ⁇ m.
• the plastic material In the case of a security element that is applied to the document surface, however, it can also make sense to design the plastic material as a thin layer of lacquer. Here it is advisable to prepare the layer structure on a separate film and then transfer it to the document. This can be particularly advantageous if the security element additionally has a diffraction structure in the form of a relief structure which has been embossed into the plastic material.
• the plastic material can also have other safety-relevant features, such as a coloring with glazing colors and / or luminescent substances.
• the magnetic coding 20 is arranged in the edge region of the plastic material 7. Represented here by a magnetic area 5.
• a further opaque layer 8 can be arranged under the coding 20 his.
• This layer 8 can either be provided in the form of a strip over the entire length of the security element 2 or only in the areas 5 of the coding 20 coated with magnetic material.
• the opaque layer 8 preferably consists of the same material as the opaque layer 3 or at least has the same color tone as the opaque layer 3. However, it can also consist of a material that contrasts in color with the opaque layer 3.
• the opaque layer 3 is arranged above the coding 20 and covers not only the coding 20 but also the other areas of the plastic layer 7 and is only interrupted in places in the form of the negative signs 4.
• This thread 2 can be produced in a very simple and efficient manner.
• the plastic material 7 is printed with the lower opaque layer 8.
• the magnetic layer 5 and, at the same time, a soluble ink layer in the area of the later characters 4 are applied in one printing process or in two successive printing processes.
• the opaque layer 3, preferably aluminum, is vapor-deposited over the entire thread material.
• the soluble printing ink is dissolved in the area of the characters 4 with a suitable solvent and the metal is thus removed in these areas, so that the negative characters 4 are formed.
• FIG. 4 shows an alternative layer structure, as is obtained in a section along AA in FIG. 2 according to the invention.
• the coding 20 or the magnetic material 5 and the opaque layer 3 with the negative signs 4 are arranged on different surfaces of the plastic material 7.
• the magnetic coding is covered on both sides by opaque layers 3 and 8.
• the opaque layer 8 can be dispensed with if magnetic iron material is used for the magnetic areas of the coding 20 or the magnetic areas 5 of the coding 20 which, in contrast to the dark magnetic materials usually used, has a light intrinsic color.
• the plastic material 7 is provided with a semitransparent metal layer 9, which is applied either by raster application of an opaque metal layer or by vapor deposition of a very thin, continuous metal layer is generated.
• Magnetic coding 20 is applied to this layer, which is then covered with an opaque, preferably black, printing ink 3 and, at the same time, negative signs 4 are generated.
• a semi-transparent metal layer 10 is again provided over the entire element layer structure in a last step. Due to the semitransparency of layers 9 and 10, cutouts 4 remain recognizable in transmitted light.
• the coding 20 extends over the entire width of the thread. It is composed of areas 5, which are provided with magnetic material, and areas 15 free of magnetic layers.
• the code 20 consists of bit cells of the same size, which are either filled with magnetic material (eg binary "1") or not (eg binary "0").
• the magnetic layer-free regions 15 of the coding 20 are used to arrange the cutouts 4 which can be seen in transmission. In this way, negative writing 4 and magnetic coding 20 can be provided together on one thread without interfering with one another.
• the recesses 4 can therefore be arranged in the middle of the thread and produced in the usual size, as in the case of threads which only have negative writing.
• the thread has the same external appearance as a conventional negative writing security thread. None reveals from the outside that a magnetic coding is simultaneously arranged on the thread.
• the idea according to the invention of arranging the cutouts 4 in the intermediate areas 15 of the coding 20 which are free of magnetic layers can also be used particularly advantageously in a coding which is composed of word and separating segments, as is known for example from EP 0 407550 AI. Because if one chooses only binary “0” for the bit sequence of the separating segments, ie bit cells free of magnetic layer, a relatively large, magnetic layer-free space is created in which the cutouts can be arranged without problems.
• recesses 16 can of course also be provided in the magnetic layer-free areas of the word segments.
• An increased protection against counterfeiting is achieved if the cutouts 16 are designed as micro-characters, i.e. have a significantly smaller size than the recesses 4. Because the micro characters cannot be imitated or can only be imitated with great effort.
• FIG. 11 A further embodiment variant is shown in FIG. 11.
• the code 20 and the negative shrub 4 or the magnetic layer 5 with the recesses 4 in between are not arranged over the entire width of the thread.
• cutouts 16 are also provided, which, as already described, differ in size from the cutouts 4.
• the basic idea of this embodiment is to provide a further magnetic layer in addition to the magnetic coding and the negative writing, whereby additional protection against forgery is achieved.
• the magnetic areas 5 of the coding 20 over another Magnetic layer 11 connected to each other.
• this magnetic layer 11 must not impair the legibility of the coding 20. Since the sensors with which the magnetic coding is read usually require a strong signal, the magnetic material 5 of the coding 20 must have a certain minimum thickness. For a purely magnetic "continuity test" along the thread 2, however, a substantially smaller layer thickness would be sufficient. This means that the magnetic layer 11 must have a smaller thickness than the magnetic layer 5, so that a sensor which is to detect the coding 20 has no signal received by the magnetic layer 11.
• This magnetic pattern can also be produced in a simple manner by first printing the film 7 with a magnetic strip in the thickness of the magnetic layer 11 and then applying a magnetic layer in the regions 5 in a second printing process, the layer thickness of which is precisely the difference between the layer thickness corresponds to the magnetic layer 11 and the layer thickness required for the coding 20.
• the second magnetic layer 12 is also applied in the form of a coding that is identical to the Coding 20 is.
• this second coding is applied parallel to the first coding and the cutouts 4 are arranged between them.
• the codings can be arranged symmetrically or asymmetrically to the cutouts 4.
• the codes can also be provided in a different arrangement on the element, it is only necessary to ensure that the negative writing 4 is not covered.
• the second magnetic layer 13 is also applied in the form of a coding. However, this is a negative representation of the first code 20.
• the two codes are applied in parallel and exactly with a gap to one another, so that a test results along the thread results in a continuous magnetic signal.
• the security element can be subdivided into partial areas, here I, II, III. At least there is in the individual sub-areas once the complete coding 20 and a negative lettering 4. Both are arranged parallel to each other. In sub-area II, however, the arrangement of negative writing 4 and coding 20 changes relative to the arrangement in sub-area I. In the present case, it is a rotation of 180 °. However, it would also be possible to arrange the partial areas in different orientations to one another. In the case of wider security elements, for example, the internal structure of the partial areas could be identical and only the orientation of the partial areas relative to one another could vary, for example by arranging them at different angles to one another.
• FIG. 12 shows a security document 1 in a top view, on the surface of which a security element 25 is arranged.
• This security element 25 has an optically variable structure which, when the viewing angle changes, produces a change in the color impression of the information displayed and / or reveals other information.
• the example shown is an embossed diffraction structure which is combined with a metal layer, so that the information stored in the diffraction structure can be recognized by the viewer in reflection.
• FIG. 13 shows a section along A - A which makes the layer structure of the security element 25 clear.
• the document of value 1 is provided with a lacquer layer 27 which is applied in the form of a coding, for example a bar code.
• This paint layer contains magnetic pigments that can be detected by machine.
• a full-surface further lacquer layer 28 which does not contain any magnetic pigments and primarily serves to compensate for the surface roughness of document 1 and to ensure good adhesion to the following layers.
• an adhesive layer 29 which can consist, for example, of a lacquer or a hot-melt adhesive.
• This adhesive layer 29 is followed by a metal layer 30, the surface of which has a relief structure which represents the diffraction structure.
• This metal layer 30 contains cutouts 31 in the form of characters, patterns or the like, which represent additional visually visible information.
• a further lacquer layer 32 is arranged over the metal layer. This can consist of any material, such as UN-curable polymers or polymers that can be initiated by UN radiation, or thermoplastic materials.
• the lacquer layer 32, the metal layer 30 and the adhesive layer 29 are advantageously prepared on a separate carrier layer and then connected to the value document material 1 after the lacquer layers 27 and 28 have been applied. The carrier material is then removed from the lacquer layer 32.
• the magnetic layer 27 is usually printed on using any printing method, it is very easy to apply the magnetic coding in the areas of the security element 25 in which there are no cutouts 31.
• Additional additives can be integrated into the second lacquer layer 28, such as, for example, color pigments, luminescent pigments or effect or gloss pigments.
• the security elements according to the invention can be used advantageously not only on or in banknotes, but also on any other documents, such as checks, ID cards or the like.
